Hi, everyone,
I'm doing an app in the App designer and I got the following problem. I have some components and I need to do some process (always the same) when any of the components value changes. I would like to know if there is a way to put everything together in the same callback. This is something that will help me to avoid repetition of lines in the code.
I'm doing something like
ValueChanged callback in component one
Calculation ComponentOne.Value+ComponentTwo.Value
ValueChanged callback in component two
Calculation ComponentOne.Value+ComponentTwo.Value
What I would like to do is
ValueChanged callback in component one or two
Calculation ComponentOne.Value+ComponentTwo.Value
Thanks in advance

Write it in a helper function, and in the callback, call the function

You can assign the same function as callback to multiple ui components.
Inside you function you will need to be able to access the properties under app directly.
function CommonValueChanged(app, event)
app.ComponentOne.Value + app.ComponentTwo.Value
end

Thats not what I meant.
You can right click on each component on the right hand pane.
For the first component, click add value changed fcn to create a callback. For the second component, Click Select Exisiting Callback and set it to same callback as one.
I have also attached a small demo.
